[martin-gaievski]

What is the bug?

Rolling upgrade BWC tests are failing for main branch:

./gradlew :qa:rolling-upgrade:testRollingUpgrade -D'tests.bwc.version=2.14.0-SNAPSHOT'

> Task :qa:rolling-upgrade:testAgainstOneThirdUpgradedCluster FAILED

FAILURE: Build failed with an exception.

How can one reproduce the bug?

Get main of this repo, run ./gradlew :qa:rolling-upgrade:testRollingUpgrade -D'tests.bwc.version=2.14.0-SNAPSHOT'

What is the expected behavior?

Tests are passing

What is your host/environment?

Issue happens only on Linux, for Win platform everything works.
